Receving poor remuneration, lumberjack's work generates sympathy (6,7)
I believe the answer is:
fellow feeling
'sympathy' is the definition.
(synonyms)
'receving poor remuneration lumberjack's work' is the wordplay.
I cannot quite see how this works, but
'poor' could be 'low' (similar in meaning) and 'low' is found within the answer.
This explanation may well be incorrect...
'generates' acts as a link.
Can you help me to learn more?
(Other definitions for fellow feeling that I've seen before include "Sympathy" , "Shared empathy" .)
